Have had mobile radios HF/VHF/UHF plus business radios & custom stereo equipment in past four trucks but none have any touch screens, electronic everything plus pile of onboard computers/ECMs like this new Colorado. Last seven trucks were all Mopars but Fiat is fast ruining the Dodge/Chrysler lines. Were supposed to re-release the Dakota's in 2019/2020/2021 and now say will be a re-badged Fiat in 2024 with 480 pound cargo capacity but only in South America & Europe. So after a lifetime of only buying Mopar trucks ordered a GM for first time since my 1972 Chevelle in high school. Have a few options for this truck and for HF radios have a Kenwood TS-480 sitting unused and now two Icom 7100s new in box one has sat almost two years with no home as work and home shack have more radios than I can use. Have a Yaesu FT 8900R 70cm/2/6/10 meter quad band mobile sitting in box unused but have my eyes on an Icom 5100 dual band D-Star. Trying to consider best configuration, the 7100 "shack in a box" which would cover my HF needs as well as VHF/UHF D-Star then use the Yaesu 8900 quad band to have ability to monitor enough bands and talk about anywhere want. Will also be installing a 150 watt business band radio (Land Mobile) What has me waffling is had the Kenwood TS-480 installed in a 1500 Ram 4WD for a couple years and worked South America, Europe, Asia and Australia along with New Zealand and chatted almost weekly with a station in Tasmania on a 20 meter hamstick. Like my Kenwood boat anchors to modern solid state shack radios the 480 mobile talks and always got great signal reports. If use the Kenwood HF then will for sure install an Icom 5100 to handle my VHF/UHF/D-Star needs. My biggest concern is RFI issues with the radios and boatload of electronics in the new Chevy Colorado Long Box 4WD WT. It has power everything, WiFi hotspot, dash/cab/backup cameras, "parking assist", towing package added a feature that almost takes over the truck and centers ball on hitch under tongue of trailer, Bluetooth, USB ports, two touch screens and more. First truck I purchased with OBD and an ECM smoked the ECM three times in under a year before figured out had HF antenna too close to ECM and if turned amplifier on to make contact then ragchewed anymore than a couple minutes truck died in the road and had to go back to the dealer. With all the onboard electronics such as computer controlled 8 speed automatic transmission, traction control computer turning locking rear differential, 4WD on/off plus applying brakes and power to each wheel as it feels necessary to keep truck planted I am sensing I could burn this truck down if installation is not spot on. For now have decided to not install my 500 watt solid state amplifier as worried key down when truck is trying to shift gears in combination with engaging traction control and 500 watts may cause some confusion for truck, especially if just pressed a button to send three PSK 31 macros on 30 meters while talking on my 150 watt VHF business radio. Newest truck I own is a 2007 with no touch screens or even 1/4 of the electronic systems the new Colorado forces the buyer into. Plan is to install a quality 70cm/2 meter dual band antenna, Comet/Diamond 70cm/2/6/10 meter Quad Band and a screwdriver. Due to tight spaces drive regularly (basically live in my truck three or four days per week working) looking at either the Baby Tarhill or Little Tarhill II for my HF stick as reason removed my Icom 706 from current work truck was got sick of stopping the truck and swapping hamsticks if wanted to change bands. Put a Texas Bug Catcher with Icom external tuner on truck but with 12.5' height from rear bumper was breaking the mast or upper fiberglass section monthly and replacing the metal shop on top almost weekly. Cannot have anything resembling a big antenna survive the way I work my trucks. Deposit and order for build was accepted by GM from my local Chevy dealer officially nine days ago with estimated build time of eight to twelve weeks. All the dash cams and even ballistic door liners, ballistic window tint, bed liner, rail caps, toolbox, skid plates, every WeatherTech accessory installed by dealer along with cold air box, cat back exhaust upgrade and RackBack headache rack with three antenna mounts installed by dealer just leaving me radios to install. It's an extended cab with back seats nobody over the age of eight could ride in so removing the rear seats, cup holders, etc and building a box to house ham radios, stereo amplifiers, subwoofers plus a hidden compartment with police style auto lock/unlock rifle rack for my truck rifle. My bigger trucks get similar box under rear seat and smaller trucks rear of cab get a custom box that makes installation of electronics much more elegant and attractive covered to match vehicle trim, hide all equipment and wiring. Also having to figure out how to get subwoofer preamp outputs from a truck that has no traditional stereo, just links to a Bluetooth device to input audio which sure I will have. Truck will also have a Wilson Cell Phone Booster which locates cell antenna outside and boosts power from 1/3 watt allowed in handheld phone to full five watts. When working in fringe/no coverage areas being able to call clients on phone is a huge benefit. Have installed multiple towers (American Tower Dealer), do subcontract cell tower maintenance and upgrades for Ma Bell as well as emergency power systems. Repair radar, hack marine radars into ground or air systems, can work on a myriad of electronics but this new truck has me concerned will burn up some expensive factory system. Ordered the biggest alternator and dual batteries from factory to not starve anything for power but just have a nagging feeling something is going to go awry. Plan to bond cab and bed to frame along with hood and front fenders getting ground straps to frame. Who has loaded a late model vehicle with lots of radio equipment and what tips do you have for someone leaping 15 years forward in truck technology and mixing in multiple radios?
